The detection method of down control channel, subscriber equipment and base station
Technical field
The present invention relates to the communications field, in particular to a kind of detection method, subscriber equipment and base station of down control channel.
Background technology
Long Term Evolution (LTE, Long Term Evolution) radio frames (radio frame) in the system comprises Frequency Division Duplexing (FDD) (FDD, Frequency Division Duplex) frame structure of pattern and time division duplex (TDD, Time Division Duplex) pattern.The frame structure of fdd mode, as shown in Figure 1, the radio frames of 10 milliseconds (ms) is 0.5ms by 20 length, and the time slot (slot) of numbering 0～19 is formed, and it is subframe (subframe) i of 1ms that time slot 2i and 2i+1 form length.The frame structure of tdd mode, as shown in Figure 2, the radio frames of a 10ms is longly formed for the field of 5ms (half frame) by two, and a field comprises that 5 length are the subframe of 1ms, and subframe i is defined as 2 and longly is time slot 2i and the 2i+1 of 0.5ms.In above-mentioned two kinds of frame structures, for standard cyclic prefix (Normal CP, Normal Cyclic Prefix), the symbol that it is 66.7 microseconds (us) that time slot comprises 7 length, wherein the CP length of first symbol is 5.2lus, and the length of all the other 6 symbols is 4.69us; For extended cyclic prefix (Extended CP, Extended Cyclic Prefix), a time slot comprises 6 symbols, and the CP length of all symbols is 16.67us.
The version number of LTE is corresponding to R8 (Release 8), and its version number that increases the version correspondence is R9 (Release 9), and for from now on LTE-Advance, its version number is R10 (Release 10) just.Following three kinds of downlink physical control channels have been defined among the LTE: physical down control format indicating channel (PCFICH, Physical Control Format Indicator Channel); The automatic repeat requests indicating channel of physical mixed (PHICH, Physical Hybrid Automatic Retransmission Request Indicator Channel); Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel).
Wherein, the PCFICH loaded information is used in reference to the OFDM (OFDM that is shown in transmission PDCCH in the subframe, Orthogonal Frequency Division Multiplexing) number of symbol, on first OFDM symbol of subframe, send, (ID Identity) determines the place frequency location by system descending bandwidth and cell ID.
PHICH is used to carry acknowledgement/non-acknowledgement (ACK/NACK) feedback information of uplink transmission data.The number of PHICH, time-frequency position can be determined by system message and the sub-district ID in the Physical Broadcast Channel (PBCH, Physical Broadcast Channel) of the descending carrier at PHICH place.
PDCCH is used for bearing downlink control information (DCI, Downlink Control Information), comprising: uplink and downlink schedule information, and uplink power control information.The form of DCI (DCI format) is divided into following several: DCI format 0, DCI format 1, DCI format 1A, DCI format 1B, DCI format 1C, DCI format 1D, DCI format 2, DCI format 2A, DCI format 3 and DCI format 3A etc.; Wherein:
DCI format 0 is used to indicate the scheduling of Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel);
DCI format 1, DCI format 1A, DCI format 1B, DCI format 1C, DCI format 1D are used for the different mode of a PDSCH code word scheduling;
DCI format 2, DCI format 2A, DCI format 2B are used for the different mode of space division multiplexing;
DCI format 3, DCI format 3A are used for the different mode of the power control instruction of Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) and PUSCH.
The physical resource of physical downlink control channel PDCCH transmission is with control channel element (CCE, Control Channel Element) be unit, the size of a CCE is 9 resource element group (REG, Resource Element Group), i.e. 36 resource elements (Resource Element), a PDCCH may take 1,2,4 or 8 CCE.These four kinds of PDCCH sizes for taking 1,2,4,8 CCE adopt tree-shaped polymerization (Aggregration), and the PDCCH that promptly takies 1 CCE can be from any CCE position; The PDCCH that takies 2 CCE is from even number CCE position; The CCE position of the integral multiple of the PDCCH that takies 4 CCE since 4; The CCE position of the integral multiple of the PDCCH that takies 8 CCE since 8.
Each polymerization rank (Aggregration level) definition search volume (Search space) comprises the search volume of public (common) and the search volume of subscriber equipment (UE, User Equipment) proprietary (UE-Specific).OFDM symbolic number that the controlled area that the CCE number of whole search volume is indicated by PCFICH in each descending sub frame is shared and the group number of PHICH are determined.UE DCI format by transmission mode of living in the search volume carries out blind Detecting to all possible PDCCH code checks.
In k subframe, the control domain of carrying PDCCH is 0 to N by suite number CCE, k-1 N CCE, kIndividual CCE constitutes.The PDCCH that UE should detect one group of candidate in each non-DRX (non-Discontinuous Reception, non-discontinuous reception) subframe to be to obtain control information, detects to be meant according to all DCI format to be detected PDCCH in organizing is decoded.The candidate PDCCH (PDCCH candidate) that need to detect defines in the mode of search volume, to polymerization grade (aggregation level) L ∈ 1,2,4,8}, search volume
